Dimensões internas nasais de crianças com fissura de lábio e palato unilateral aferidas por rinometria acústica
Keywords in Portuguese
Cavidade nasal

rinometria acústica
Abstract in Portuguese
Objetivo: Analisar as áreas seccionais, distâncias e volumes de segmentos específicos da cavidade nasal de crianças com fissura de lábio e palato unilateral, comparativamente a crianças sem fissura, por rinometria acústica. Modelo: Estudo prospectivo. Local de Execução: Laboratório de Fisiologia, HRAC-USP. Participantes: Trinta e nove crianças com fissura transforame unilateral e 34 crianças sem fissura, de ambos os sexos, com idade de 6 a 9 anos. Intervenções/Variáveis: Foram avaliadas as áreas seccionais correspondentes ao 2º, 3º e 4º entalhes do rinograma (AST1, AST2 e AST3), suas respectivas distâncias (d1, d2, d3) e os volumes nos segmentos correspondentes a 1-3,2cm (V1), 3,3-6,4cm (V2) e 7-12cm (V3), relativamente à narina, antes e após a aplicação tópica de vasoconstritor nasal (VC), utilizando um Rinômetro Acústico Eccovision-Hood Laboratories. Resultados: No lado fissurado (LF) as médias (±DP) de AST1, AST2, AST3 (em cm2), d1, d2 e d3 (em cm) e V1, V2 e V3 (em cm3) foram: 0,17±0,12, 0,29±0,20, 0,40±0,28, 2,02±0,40, 3,74±0,51, 5,50±0,44, 0,54±0,30, 1,22±0,86 e 4,52±3,37, respectivamente. No lado não-fissurado (LNF) as médias corresponderam a 0,33±0,11, 0,65±0,28, 0,90±0,43, 1,69±0,48, 3,67±0,53, 5,60±0,70, 1,04±0,37, 2,57±1,20, 8,77±4,85, respectivamente. As médias de AST e V em LF foram estatisticamente menores e a média de d1 foi maior que as observadas em LNF e no grupo controle, antes e após o uso do VC (p<0,05). A vasoconstrição provocou aumento dos valores de AST e V em ambos os grupos. Conclusão: Os resultados obtidos mostram significativo comprometimento da permeabilidade nasal em crianças com fissura labiopalatina unilateral.

Abstract in English
Objective: To evaluate cross-sectional areas, distances and volumes of specific segments of the nasal cavity of children with unilateral cleft lip and palate, compared to children without cleft, by acoustic rhinometry. Design: Prospective analysis. Setting: Laboratory of Physiology, HRAC-USP. Participants: Thirty-nine children with unilateral cleft lip and palate and 34 controls without cleft, of both genders, aged 6 to 9 years. Interventions/Variables: Cross-sectional areas measured at the 2nd, 3rd and 4th notches in the rhinogram (CSA1, CSA2 and CSA3), their distances from the nostril (d1, d2 and d3) and volumes measured at 1-3.2cm (V1), 3.3-6.4cm (V2) and 7-12cm (V3) from the nostril were evaluated by means of an Eccovision Acoustic Rhinometer-Hood Laboratories, before and after nasal decongestion. Results: At the cleft side (CS), the mean values (±SD) of CSA1, CSA2, CSA3 (in cm2), d1, d2 and d3 (in cm) and V1, V2 e V3 (in cm3) were: 0.17±0.12, 0.29±0.20, 0.40±0.28, 2.02±0.40, 3.74±0.51, 5.50±0.44, 0.54±0.30, 1.22±0.86 and 4.52±3.37, respectively. At the non-cleft side (NCS) mean values corresponded to 0.33±0.11, 0.65±0.28, 0.90±0.43, 1.69±0.48, 3.67±0.53, 5.60±0.70, 1.04±0.37, 2.57±1.20, and 8.77±4.85, respectively. CSA and V means at CS were significantly lower and d1 mean was higher than NCS and control means, before and after decongestion (p<0.05). Increased CSA and V mean values were seen after decongestion in both groups. Conclusion: The results show a significant impairment of nasal patency in children with unilateral cleft lip and palate.
